A single Schematron pattern-element.
A structure, simple or complex. A set of rules giving constraints that are in some way related. The id attribute provides a unique name for the pattern and is required for abstract patterns.
The title and p elements allow rich documentation.
The icon, see and fpi attributes allow rich interfaces and documentation.
When a pattern element has the attribute abstract with a value true, then the pattern defines an abstract pattern. An abstract pattern shall not have a is-a attribute and shall have an id attribute.
Abstract patterns allow a common definition mechanism for structures which use different names and paths, but which are at heart the same. For example, there are different table markup languages, but they all can be in large part represented as an abstract pattern where a table contains rows and rows contain entries, as defined in the following example using the default query language binding:

     <sch:pattern abstract="true" id="table">
         <sch:rule context="$table">
             <sch:assert test="$row">
             The element <sch:name/> is a table. Tables contain rows.
             </sch:assert>
         </sch:rule>
         <sch:rule context="$row">
             <sch:assert test="$entry">
             The element <sch:name/> is a table row. Rows contain entries.
             </sch:assert>
         </sch:rule>
     </sch:pattern>
 

When a pattern element has the attribute is-a with a value specifying the name of an abstract pattern, then the pattern is an instance of an abstract pattern. Such a pattern shall not contain any rule elements, but shall have param elements for all parameters used in the abstract pattern.
The following example uses the abstract pattern for tables given above to create three patterns for tables with different names or structures.

     <sch:pattern is-a="table" id="HTML_Table">
         <sch:param name="table" value="table"/>
         <sch:param name="row"   value="tr"/>
         <sch:param name="entry" value="td|th"/>
     </sch:pattern>
     <sch:pattern is-a="table" id="CALS_Table">
         <sch:param name="table" value="table"/>
         <sch:param name="row"   value=".//row"/>
         <sch:param name="entry" value="cell"/>
     </sch:pattern>
     <sch:pattern is-a="table" id="calendar">
         <sch:param name="table" value="calendar/year"/>
         <sch:param name="row"   value="week"/>
         <sch:param name="entry" value="day"/>
     </sch:pattern>
 

When creating an instance of an abstract pattern, the parameter values supplied by the param element replace the parameter references used in the abstract patterns. The examples above use the default query language binding in which the character $ is used as the delimiter for parameter references.
Thus, given the abstract patterns defined earlier in this clause, the patterns defined above are equivalent to the following, with the id elements shown expanded:

     <sch:pattern id="HTML_table">
         <sch:rule context="table">
             <sch:assert test="tr">
             The element table is a table. Tables containing rows.
             </sch:assert>
         </sch:rule>
         <sch:rule context="tr">
             <sch:assert test="td|th">
             The element tr is a table row. Rows contain entries.
             </sch:assert>
         </sch:rule>
     </sch:pattern>
     <sch:pattern id="CALS_table">
         <sch:rule context="table">
             <sch:assert test=".//row">
             The element table is a table. Tables containing rows.
             </sch:assert>
         </sch:rule>
         <sch:rule context=".//row">
             <sch:assert test="cell">
             The element row is a table row. Rows contain entries.
             </sch:assert>
         </sch:rule>
     </sch:pattern>
     <sch:pattern id="calendar">
         <sch:rule context="calendar/year">
             <sch:assert test="week">
             The element year is a table. Tables containing rows.
             </sch:assert>
         </sch:rule>
         <sch:rule context="week">
             <sch:assert test="day">
             The element week is a table row. Rows contain entries.
             </sch:assert>
         </sch:rule>
     </sch:pattern>
